Question

I want to Implement MVP pattern. I have a user control that has some Textboxes and when I put it in form I call a method from usercontrol and fill textboxes. But in mvp patt

Answer 1

Here is an example implementation of the pattern. The Presenter only knows about the interface having a show method. The Presenter calls it, but the only the form (aka View) implements how the form should be displayed.

public interface IMyFormView {
    void Show();
}

public class MyForm : IMyFormView {

    public MyForm() {
        var presenter = new MyFormPresenter(this);
        presenter.Init();
    }

    public void Show() {
        usercontrol1.fill();
    }
}

public class MyFormPresenter
{
    private IMyView _view;
    public MyFormPresenter(IMyView view) {
        _view = view;
    }

    public void Init() {
        _view.Show();
    }
}

If you need to pass data into the view, then you can pass a view model through the Show-method or set custom Properties on the view.
